Description

CABLE WITH GUIDE SHELL AND LENGTH COMPENSATION, TRANSMISSION ARRANGEMENT WITH A CABLE AND METHOD FOR ASSEMBLING A CABLE

The present invention relates to a cable, a transmission system and a method for producing a cable, for example for a transmission system for a vehicle.

In a manual transmission is a change from one gear to another gear by moving at least one control lever, which is arranged on the outside of a housing of the gearbox. To move the control lever, a pulling force is transmitted from a gear selector lever to the control lever via a cable pull. Since the pulling force is transmitted from the gear selector lever to the control lever over a longer distance, add manufacturing tolerances that can be compensated by a length adjustability of the cable.

US 2010/0275715 A1 describes a Schaltkabelkonfektion and a connector for a Schaltkabelkonfektion.

Against this background, the present invention provides an improved cable, an improved transmission system and an improved method of manufacturing a cable according to the main claims. Advantageous embodiments will become apparent from the dependent claims and the description below.

In order to make a cable length adjustable, two components of the cable, which are each connected to opposite ends of the cable, are designed to be mutually displaceable. In this case, a secure connection between the movable components is required to transmit the traction safely.

The two components can be designed latchable in predefined steps. The latching can be done by a locking element that transmits the tensile force from one component to the other component. By snapping the tensile force can be transmitted via a positive connection. A positive lock is reliable, as the locked-in to separate the positive locking Components must be moved in a direction transverse to a direction of force, which is possible only by external influence.

A cable is proposed for transmitting a tensile force to a point of articulation, the cable having the following characteristics:

an abutment for introducing a, the traction opposing force in a sheath of the cable;

a pull rod which is axially mounted in the abutment and is coupled to a wire core of the cable, wherein the pull rod at a protruding end of the abutment has a fitting with a first component of a toothing;

an adjustment unit for adjusting a length of the cable between the abutment and the articulation point, wherein the adjustment unit comprises a guide for the molding, wherein the molding is arranged in the guide axially movable and guided transversely thereto; and

a locking member for fixing the fitting in the adjustment unit, the locking member being disposed in a recess oriented transversely of the guide in the adjustment unit and being movable between a locking position and a setting position, the locking member having a second component of the teeth formed therefor to engage positively in the locking position in the first component and to prevent the axial movement of the fitting in the guide.

The cable can be used for example for a transmission system for a vehicle. Under a cable can be understood a Bowden cable. An articulation point can be a force application point for the tensile force. A shell may be a pressure-resistant hose in which the wire core of the cable is arranged. The wire core can be tensile stable. An abutment may be an end of the sheath. The pull rod can be aligned in extension of the sheath and the rope. The pull rod can be movably mounted along its main extension axis. A fitting may be a part of the tie rod made by forming a part of the pull rod. The first component may for example be embossed or cut into the fitting. The adjustment unit can be connected directly to the be connected steering point. The molding may be movable within an adjustment range in the guide of the adjustment unit. The locking element may have transverse to the tensile force aligned contact surfaces to the adjustment. The second component of the gearing may provide contact surfaces to the fitting that are engaged only in the locking position.

The toothing may preferably have a pitch less than one millimeter, more preferably less than three quarters of a millimeter, or more preferably less than half a millimeter. By an advantageous combination of materials in the toothing, the tensile force can be transmitted over such small teeth. As a result, the length of the cable can be set very accurately.

The locking element may have an insert. This insert can be made of a material that is higher loadable than the material from which the rest of the locking element is formed. A higher loadable material may have higher tensile strength, compressive strength and / or shear strength than a lower loadable material. For example, the locking element may comprise a locking insert of a material having a greater tensile strength, compressive strength and / or shear strength than a material of the locking base body. In this case, at least a part of the second component of the toothing can be formed on the insert. With a higher loadable material, a large amount of force can be transmitted over a small area without causing material damage. By a higher loadable material, the locking element can be made compact.

For example, the material of the insert may be a metallic material and the material of the locking element may be a plastic material. A metallic material may provide a pair of materials with the fitting that is more resilient than a pair of materials between the plastic material and the fitting.

The shaped piece can have a quadrangular cross section, wherein the first component of the toothing can be arranged on two opposite side faces of the shaped piece. This allows the first component in a movement be aligned tion direction of the locking element. Thus, the teeth of the locking element can be introduced into the teeth of the fitting.

The locking element may have a U-shape, wherein the second component of the toothing is arranged on the inner sides of the legs of the U. Due to the U-shape, the fitting can be enclosed on at least two sides. By the U-shape lateral ejection forces that result in the tensile force in the toothing can be supported in the U to prevent slippage of the teeth.

The fitting may have a thickening at an end opposite the pull rod which projects beyond the first component of the toothing. In this case, the thickening abut on side walls of the guide and the first component have a distance from the side walls. The thickening may be designed as a stop to provide a loss of security.

The locking element may have at least one latching nose, which is designed to engage positively in the setting position on a first body edge of the setting unit in order to secure the locking element against removal from the recess. The locking lug may be designed to engage positively in the locking position on a second body edge of the setting unit in order to secure the locking element against removal from the locking position. The detent may have a bevel through which the latch is pressed into the recess when moving into the locking position. By latching in the set position and the lock position, lateral forces that move the lock member from the lock position to the set position or from the set position out of the recess may be intercepted. The bevel allows tool-free movement of the locking element into the setting position and from the setting position into the locking position.

The locking element may have a sliding surface for the first component of the toothing. In this case, the sliding surface may be arranged in the adjustment position adjacent to the first component and offset in the locking position be arranged to the toothing. A sliding surface may be aligned in a plane with tooth tips of the first component. The sliding surface can prevent tilting of the fitting in the guide and allow a defined axial movement of the fitting in the guide. The sliding surface can be used in the adjustable state as a stop for the thickening of the molding to define the adjustment and to prevent accidental disconnection of the adjustment and the tie rod.

The toothing can be formed with insertion bevels. By at least one insertion bevel, blocking of the first component and the second component when moving the locking element from the setting position to the locking position can be prevented.

Furthermore, a transmission system with a transmission with an articulation point and with a selector lever is presented. The transmission system further comprises a cable according to the approach presented here, wherein the cable connects the selector lever with the articulation point and is adapted to transmit a tensile force from the selector lever to the articulation point, wherein two abutment disposed at opposite ends of the sheath are formed to support the counterforce to the tensile force.

Furthermore, a method for producing a cable is presented, wherein the method comprises the following steps:

Providing a tie rod, coupled to a wire core of the cable, to a fitting having a first component of teeth, the tie rod being axially supported in an abutment connected to a sheath of the cable;

Providing an adjustment unit for adjusting a length of the cable between the abutment and the point of articulation, the adjustment unit having a guide for receiving the fitting and a recess for receiving a locking element; Providing the locking element for fixing the shaped part in the setting unit, wherein the locking element has a second component of the toothing, which is designed to engage in a form-fitting manner in the first component and to prevent the axial movement of the shaped part in the guide;

Placing the fitting in the guide of the adjustment unit; and

Pressing the locking element into the recess until the locking element is arranged in a setting position in which the fitting is loss-resistant connected to the adjusting device.

In the following description of preferred embodiments of the present invention, the same or similar reference numerals are used for the elements shown in the various figures and similarly acting, wherein a repeated description of these elements is omitted.

1 shows an illustration of a cable pull 100 with a stepless length adjustment device 102. The cable pull 100 is shown in a three-dimensional representation. The cable 100 has a wire core, not shown here, for transmitting a tensile force. The wire core is guided in a flexible sheath, also not shown. The shell is tubular. The cable 100 may also be referred to as a Bowden cable. The sheath terminates in an abutment 104 at both ends. The abutment 104 is supported at a fixed point to transmit a counterforce to the traction force. Thus, the shell is subjected to a compressive force, which is in each case oriented opposite to the tensile force. The abutment 104 has a rigid sleeve 106, which is designed as a linear sliding bearing for a pull rod 108. The sleeve 106 is aligned in extension of the sheath to ensure a tangential connection of the rope to the tie rod 108. The tie rod 108 is flattened at an exposed end and has an axially aligned slot in the flattened portion. The flattened part is inserted into an end piece 1 10 and clamped using a screw 1 12 in the end-piece frictionally. The screw is executed here by a hexagon screw and secured against rotation nut. The end piece 1 10 has a ball bushing 1 14, which is adapted to transmit the tensile force to a ball pin as a point of articulation.

2 shows an illustration of a cable pull 100 with a pull rod 108 for a stepless length adjustment device. The cable 100 essentially corresponds to the cable pull in FIG. 1. In contrast, here is the tie rod 108 with the flattened end 200 shown without attached parts. The slot 202 is arranged centrally in the end 200.

In the cable pull 100 shown in FIGS. 1 and 2, the cable pull adjustment takes place steplessly by means of a screw connection.

3 shows an illustration of a cable pull 100 with positive force transmission according to an embodiment of the present invention. The cable 100 is shown in a three-dimensional representation. The cable 100 is adapted to transmit a tensile force to a point of articulation. The cable 100 has an abutment 104, a pull rod 108, an adjustment unit 300 and a locking element 302. The abutment 104 is designed to initiate an opposing force directed counter to the tensile force into an envelope of the cable 100. The pull rod 108 is axially mounted in the abutment 104 and coupled to a wire core of the cable 100. The pull rod 108 has at a protruding end of the abutment 104 on a fitting 304 with a first component of a toothing. The adjustment unit 300 is configured to adjust a length of the cable 100 between the abutment 104 and the point of articulation. The adjustment unit 300 has a guide for the molding 304. The molding 304 is axially movable in the guide and arranged to be guided transversely thereto. The locking element 302 is configured to fix the molding 304 in the adjustment unit 300. The locking element 302 is arranged in a recess oriented transversely to the guide in the setting unit 300. The locking member 302 is movable between a locking position and a setting position. The locking element 302 has a second component of the toothing. The second component is designed to engage positively in the locking position in the first component and to prevent the axial movement of the molded piece 304 in the guide. The second component is formed in mirror image to the first component. The locking element 302 is shown here in the locking position.

In one embodiment, Fig. 3 shows a cable pull adjustment 300 with 0.5 mm detent. With the approach presented here, package advantages can be be enough. Likewise, the cable 100 can be easily adjusted with the approach presented here. Due to the positive connection of the locking by means of clips a security of the connection can be increased despite adjustability. The snap-action of less than 0.5 mm ensures a correct system setting "gearbox / gearshift." Furthermore, the positive-locking connection can transmit high actuating forces of greater than 1000N.

In one embodiment, a compression spring is disposed between end piece 300 and slider 106 to eliminate play directly during assembly.

The molding 304 has a quadrangular cross-section. The first component of the toothing is arranged on two opposite side surfaces of the molding 304. The teeth have a pitch less than half a millimeter. Previously, teeth with a tooth pitch of one millimeter or larger were executable. The approach presented here now allows teeth with a smaller pitch, the pitch <1 millimeter, <0.75 millimeters or, as shown, may be <0.5 millimeters. The toothing has elongated teeth which are aligned transversely to an axis of the tie rod 108. The molding 304 has at a, the pull rod 108 opposite end of a thickening 400, which projects beyond the first component of the toothing.

The quick adjustment system includes a ball bushing 14, an end piece 300, a slide pin 108, a quick adjustment 302, and cable abutment 104. The ball bush 1 14 is connectable to a ball stud. The quick setting 302 can be deactivated and activated, as well as locked in both states. 5 shows an illustration of a cable pull 100 in an adjustable state according to an embodiment of the present invention. The cable corresponds essentially to the cable shown in Fig. 3. The abutment and the sleeve are not shown here. The locking element 302 is shown here in the set position. The locking element 302 is disposed in the recess of the setting unit 300 and locked in the set position. The adjustment position corresponds to an intermediate position of the locking element 302, while the locking position corresponds to an end position of the locking element 302 in the recess.

6 shows a detailed representation of a cable pull 100 in the locked state according to an exemplary embodiment of the present invention. The cable 100 substantially corresponds to the cable shown in Fig. 3. The cable 100 is shown here in comparison to FIG. 3 from an opposite side. The locking element 302 is substantially U-shaped. In this case, the locking element 302 on two similar legs, between which the molding 304 is arranged. The legs each have a part of the first component of the toothing on their inner sides. In the locked state, the components of the toothing of fitting 304 and locking element 302 engage each other and form the positive connection. The locking element 302 has at least one latching lug 600. The locking lug is arranged on a side facing away from the molding 304 side of the legs. The locking lug 600 is designed to engage positively in the locking position on a body edge 602 of the setting unit 300 in order to secure the locking element 302 against removal from the locking position. By pushing back the latching lugs 600, the locking element 302 can be unlocked and moved from the locking position to the setting position. Then the length of the cable 100 can be readjusted.

In the exemplary embodiment shown, the locking element 302 has two opposite latching noses 600, which are latched on two opposite body edges 602. The body edges are formed here by edges of the recess 604. The adjustment unit 300 has pockets 606 in the side walls. The pockets 606 each provide a second body edge for latching the locking lugs 600 in the adjustment position. The pockets 606 are formed here as breakthroughs.

In one embodiment, not shown, the body edges for the latching position 602 are formed by further pockets in side walls of the recess 604.

The locking element 302 has at least one sliding surface 608 for the first component of the toothing. The sliding surface 608 is disposed in the setting position adjacent to the first component. In the locking position, the sliding surface 608 as shown here is offset from the toothing arranged.

The sliding surfaces 608 and the second component of the toothing are arranged in a plane, wherein the direction of movement of the locking element 302 between the locked state and the adjustable state lies in the plane.

Fig. 7 shows a side view of a cable 100 in an adjustable state according to an embodiment of the present invention. The cable 100 substantially corresponds to the cable shown in Fig. 5. The locking member 302 is disposed in the adjustment position in which the molding 304 is axially movable in the guide. The locking lug 600 is designed to engage in a form-fitting manner in the setting position on a body edge 606 of the setting unit 300, in order to secure the locking element 302 against removal from the recess. Through the opening 606 can be seen how the locking lug 600 is engaged on the second body edge 606. As a result, the locking element 302 is loss-protected. The locking element 302 has a circumferential flange 700, which is in the adjusted position spaced from the setting unit 300.

In other words, the pre-catch is clipped in Fig. 7 in the delivery state. Fig. 8 shows a side view of a cable 100 in the locked state according to an embodiment of the present invention. The cable 100 corresponds to the cable in Fig. 7. Here, the locking member 302 is disposed in the locking position in which the molding 304 is axially fixed. The locking lug 600 is latched to the body edge 602. The flange 700 is now located on the adjustment unit 300.

Fig. 9 shows a cross-sectional view of a cable pull 1 00 in an adjustable state according to an embodiment of the present invention. The cross section is perpendicular through the locking element 302 in the adjusted position. The locking cable 600 has a bevel through which the locking lug 600 is pressed into the recess 604 when moving from the setting position into the locking position. Upon reaching the locking position, the locking lug snaps back over the body edge 602. In addition, it is shown here that the locking element 302 has an insert 900 made of a material that can be loaded higher than a material of the locking element 302, wherein on the insert 900 at least a part of the second component of the Teeth is formed. The insert 900 comprises a metallic material. The locking element 302 has a plastic material. The flange 700 of the locking element 302 is designed in two layers. The insert 900 forms a metal cover layer which is disposed on a lower layer of plastic. The insert 900 is arranged in a central recess of the locking element 302. The insert 900, like the locking element 302 except for the flange 700, has a U-shape. On the inner sides of the legs of the insert 900, the second component of the toothing is arranged. The toothing is formed with insertion bevels.

In one embodiment, the requirements for the positive connection by locking by means of clips, the adjustability with a maximum of 0.5 mm detent and the transmission forces of the positive connection of greater than 1000N by a metallic inserter 900 in the locking element 300 are met. Here, the metallic inserter 900 latching steps of less than 0.5 mm. So that the locking element 302 also cleans in intermediate positions. can be locked, the teeth of the detent are executed with a Einführfase.

In one embodiment, the metallic inserter 900 is made of sintered metal.

In one embodiment, the metallic inserter 900 is formed by powder injection molding, metal injection molding MIM.

In one embodiment, with reduced requirements regarding the transmission force in the cable, the insert 900 of the locking element 302 is made of high-strength plastic.

In other words, Fig. 9 shows a quick adjustment 302 with two components 900. The insert can also be referred to as a latching element.

Fig. 10 shows a longitudinal sectional view of a cable 100 in an adjustable state according to an embodiment of the present invention. The longitudinal section extends through the locking element 302 in the setting position and vertically by the setting unit 300. Thus, the cable 100 substantially corresponds to the cable in Fig. 7. The molding 304 has, as in Fig. 4, the thickening 400 at the end facing away from the tie rod 108 on. The thickening 400 abuts against side walls of the guide. Thus, the first component of the toothing has a distance from the side walls. The sliding surfaces 608 of the locking element 302 abut in the setting position on the first component of the toothing and thus allow a guided axial displacement of the drawbar 108 within the setting unit 300. The thickening 400 is wider than the distance between the sliding surfaces 608. As a result, the thickening 400 abuts at the end of the adjustment on the locking element 302 and prevents falling out of the tie rod 108 from the guide in the setting unit 300. The thickening 400 acts as a loss or loss. Within an adjustment range 1000, the pull rod 108 can be moved axially with the shaped piece 304 in the guide. In one embodiment, the adjustment range 1000 is reduced to ten millimeters.

Fig. 1 1 shows a cross-sectional view of a cable 100 in the locked state according to an embodiment of the present invention. The cross section runs perpendicularly through the locking element 302 as in FIG. 9. In this way, the cable pull 100 essentially corresponds to the cable pull in FIG. 8. The locking element 302 is shown here in the locking position. Thus, the sliding surfaces 608 are displaced parallel to the first component of the toothing and the locking lugs 600 engage around the edge of the recess 604. In the locked state, the second component of the toothing engages the first component in a form-fitting manner.

As the latch member 300 moves from the set position to the lock position, the resilient detents are forced into the recess 604 by the slope at one edge of the pockets 606, slide along the side surfaces of the recess and snap back to the edge of the recess.

Fig. 12 shows a longitudinal sectional view of a cable 100 in the locked state according to an embodiment of the present invention. The longitudinal section extends through the locking element 302 in the locking position and vertically by the adjustment unit 300. Thus, the cable 100 substantially corresponds to the cable in Fig. 10. As shown in Fig. 1 1 engages the arranged on the fitting 304 first component of the teeth form fit in the arranged on the locking element 302 second component of the toothing. As a result, the axial mobility of the molded piece 304 is prevented in the guide.

In the illustrated embodiment, the pull rod 108 is inserted with the fitting 304 maximum far into the guide and fixed.

FIG. 13 shows a spatial representation of a locking element 302 according to an embodiment of the present invention. The locking mechanism Element 302 is shown here individually. The locking element 302 essentially corresponds to the locking element shown in FIG. 9. As in FIG. 9, the locking element 302 has an insert 900, which has the second component of the toothing. The insert 900 is enclosed in a plastic part which has a locking mechanism 1300 of the locking element 302. The second component of the toothing projects beyond a plane of the sliding surface 608 by a tooth depth. At an end facing the sliding surface, the teeth run out into inlet slopes or chamfers in order to simplify threading of the second component into the first component. Each leg of the locking element 302 has on an outer side a pocket 1302 in which a flexible tongue 1304 is arranged. Each tongue 1304 has one of the latching noses 600. The tongues 1304 are designed as mechanical springs and are designed to counteract deformation by a defined counterforce.

Fig. 14 shows a view of a locking element 302 according to an embodiment of the present invention. The locking element 302 essentially corresponds to the locking element in FIG. 13. Here, the U-shape of the locking element 302 with its two legs is particularly clearly visible. Each leg has on its inner side depending on a sliding surface 608 and a part of the second component of the toothing. The sliding surfaces 608 are each formed with a chamfer to facilitate the insertion of the locking element 302 into the recess of the setting unit. On its outer side, the leg has the locking mechanism 1300 with the tongue and the locking lug 600. The locking lugs 600 are each over the level of the outside over.
